Description

The ability to predict how a data communications network will perform in terms of delay, throughput or packet loss is an important aspect of the engineering practice of computer and telecommunications network design. Given the complexity of operation of communications protocols, coupled with the randomness of data traffic transported by a network, gaining a reliable estimate of system performance requires careful analysis with appropriate modelling techniques. The aim of this module is to firstly review the operating principles of data communications protocols and then to develop the basic theory and practice required for evaluating the performance of communications systems and data networks, using discrete-state mathematical and computer simulation modelling methods.

Learning Outcomes

1. Describe the basic operating principles of the protocols used to implement various layers of the OSI model and identify their basic performance parameters,
2. design and implement a disrcete-event computer simulation model for performance evaluation of a data communications network and be able to analyse the simulation output using statistical methods,
3. derive results relating to single server queuing models and networks of queues,
4. apply the analytic techniques of probability and queuing theory to calculate the performance characteristics of selected communications systems or protocols,
5. compare the achievable accuracy of the results from simulation models to that of analytic models that employ approximations to achieve a tractable solution.
